An across-the-board sell-off dragged the benchmark indices around a per cent lower on Friday as sombre global mood hit markets during the second-half of the trading session. US 10-year Treasury yields rose again on Friday, back above 1.6 per cent, and were on track to rise for the seventh straight week. Add to it, the dollar index rose 0.4 per cent denting sentiment further. Against this backdrop, gains in Asian stock markets proved tough to match for most of European peers, after they hit a 1-year high in the prior session. Nasdaq Futures, which tumbled over 1.5 per cent, or 200 points, also suggested a lower start for Wall Street later in the day.
